Abstract

A subtle interplay: In the formation of a 1.6 nm micelle containing up to six molecules of propofol, a hydrogen-bond network is shown to influence the structure of the micelle, whereas the nonpolar groups arrange in such a way that the remaining noncovalent interactions are maximized. Such globular structures present a characteristic signature in the IR spectrum that will allow their identification in more complex media.
